application med January 2e, 1914. serial no. 813,903.

Bel it known that l, EDWARD J. QUiNN, a citizen of the United States, residing at Vorcester, in the county of Worcester and Commonwealth of ,Massachusetts have invented a new and 'useful Improvement in Guides for Bolling-Mills, of which the f ollowing description, taken in connection wlthA the accompanying drawings, is a specification. The present invention relates to a guide designed to support the rod orbar 'fed to the rolls of a rolling mill in proper position tol present the same to the circumferentialv grooves or passes of the rolls. It has heretofore been found advantageous to employ a pair of cooperating guide plates, having opposed recesses in their adjacent faces, adapted to constitute a guidin aperture-for the rod or bar, and to make suc guideplates adjustable toward and away from one another, for the pupose of varying the size and shape of the aperture formed by their recesses, in order to accommodate diiferent sizes'and shapes of bars. Such adjustment has heretofore been .accomplished by anadjusting screw, adapted to .bear against, and thereby retain in adjusted position, one of said plates. However, on account of the necessity of positioning such plates in close proximity to the rolls, it has been found difficult heretofore to operate and support such a screw in favorable position to exert pressure against the adjustable guide present invention aims to overcome this difliculty; and it is a further object ofthls in# vention to provide means yfor holding the adjustable guide plate which, while adapted'to.A

present invention, the latter. being shownpartially in longitudinal section. (Fig. 2 is,

a section on line 2 2, Fig. 1.

`Like reference numerals refer to like'parts in the different figures. j

Referring to the drawings, l denotes a roll housing having journaied therein an upper plate V -at the most effective point in the same. rlhe at such a point'. [a lever 15, comprising a plate ofy substanroll 2 and a .lower roll 3. Said rolls are pro- `vided with the usual circumferential grooves or passes, that in the lower roll 3- being of the housing l is a supporting frame 6,

which in the present instance takes the form of an open ended trough-like structure,I proriding an interior chamber fl for the reception ofthe mechanism embodying this in- -vention side walls 8 and 9, which are extended for'- wardly into close proximity to the rolls 2 and 3. A. pai-r of guide plates 10Y and 11, provided on their adjacent `faces with opposed recesses to substantially embrace the bar 12, are .received withinthe forward end of the chamber 7, and projectforwardly therefrom into close proximity to the rolls 2 and 3. ln the present instance, the bar` 12 is elliptical in cross section with its majoraXis vertical, as shownin llig. 1, and its contact with the recesses of the guide plates 10 and 11 restrains it from shifting or tilting/sidewise as it is presented to the rolls. The guide plate 10 bearsv against'the verticalwall 8 of the supporting frame 6, and the guide plate 10 is held against the bottom of the frame 6 by a screw passing through the top wall Vof the frame 6, shown at 13, F ig. 1. The plates The said supporting frame 'has' 10 and l1 are held from longitudinal movement byv ribs 10a entering a Irecess Il()b in the bottom of the frame 6. rllhe guide plate 1l is free to be moved toward or away fromthe lguide plate 10 for-the purpose of varying the size of the guide way formed by the cooperating recesses of said plates. rl`he apparatus for e'ecting the said adjustment of the plates and for applying a pressure to the plate 11, comprises a screw 18 heldin the side wall 9 and rotated by a lever handle 20.

@n account ofthe location of. the plates 10 and l1 at the extreme forward end of the supporting frame', whereby for a substantial portion of their lengths they project 4'outwardly of said frame,V the use of a screw,

large enough for the purposeland bearing against the center of the plate 11, as in previous constructions is precluded by reason of the reduced size of the supporting frame To obviate this 'objection tially the saine width as the height of the guide plato 1l, is mounted edgewise within said chamber, being pivoted on a boit l@ lief mounted at the rear end of the frame, and extending forwardly to contact wlth the centralportion of the guide plate 11 by means of a projecting ledge 17. At a point intermediate itsends, the leverl is engaged by the adjusting screw 18, adapted to be moved in or out by means of the operating handle 20 which is held -on the hexagonal shank 21 of the screw 18, connection may be provided. i

It will be noted that the provision of the lever 15 enables the adjusting screw to be located at a point removed from `the guide plates 10 and 11, and also at a convenient and practicable distance from the rolls, so as to permit of its ready operation. Furthermore, owing to the increased' leverage which obtains at the forward end of the lever, a smaller degree of movement will be required for the screw than if it were in direct engagement, with the guide plate 11, as will be readilyapparent. qIn addition, by reason of the lever being placed on edge,

an effect similar to that of a stiff leaf spring` is secured, 4whereby the passage of the bar between the guide plates is rendered freer, than if the plate 1l vwere held absolutely rigid.

I claim,

1. In a guide for rolling mills,a fixed guide plate and an adjustable guide plate, and yielding means contacting with said adjustable guide plate to retain said plate against the bar ywhich is being rolled.

2. In a guide forvrolling mills, a supporting frame, a fixed guide plate and an ad-K justable guide plate, each having interlocking engagement with said supporting frame, and yielding means for retaining said adjustable guide plate in operative relation to said vfixed guide plate.

3. In a guide for rolling mills, a pair of coperating guide plates, an adjusting memj ber for one of said guide plates, and a resilient connection between said guide plate,

and said adjusting member.

4. In a guide for rolling mills, a supportor any suitable 8. In a guide said plates, and means for moving said lever against said guide plate.

6. In a guide for rolling mills, a pair of guide' plates, a levercontacting with one of said plates, and means for exerting pressure against said lever between itsends and at a. point remote from said guide plate.

7. In a guide for rolling mills, a supporting frame, a pair ofFguide :plates carriedthereby, an adjusting screw carried by said frame beyond the end of oneofasaid guide plates, and means for transmitting movement of said screw to one of said guide plates. V

for rolling mills, a supporting frame,"a pair `of guide plates carried thereby, an adjustable member carried by said frame, and resilient means for transmitting movement of said member to one of said guide plates.

9. In a guide for rolling mills, a supporting frame, a pair of guide plates carried said frame, and adapted to move one of said guide plates, and means between said adjustable member and said last'mentioned guide plate for multiplying the movement of the adjustable member.
